right-hand side of the bell housingare larger than the
other five screws.
Fit the remaining fluid coupling outer cover setscrewsand tighten them evenlyto a torque loading of
l6 l8 lb.ft. (2'21-2'49 kg.m.). lf balancing weights
are to be fitted, they must be attached with the fluid
coupling setscrews,paying particular attention to the
numbersstampedon eachweight and on the coupling
cover.
Remove the cradle and iack from beneath the
gearbox.
The gearboxand enginecan now be manoeuvredas
a unit to facilitate assemblyof the rear mountings.

brackets.
Ensure that the joint face of the engine breather
and its mating face on the crankcaseare clean, then
fit a new 'Klingerit' joint to the breather.
Fit one 'L'-shaped metal and bonded rubber plate
betweeneachofthe enginerear mountsand the chassis
frame, with the upturnedportion towards the front of
the engine. Ensure that if metal packing pieceswere
originally fitted under the enginerear mountings,they
are refitted to the same mountings from which they
were removed.
Working from beneaththe car, place into position
the left-hand fuel breatherand enginebreatherpipes.
Similarly, position the right-hand fuel breather and
slide it into the assemblyclip adjacentto the flywheel
cover. Connect the fuel breatherpipe unions and fit
and tighten the setscrewssecuringthe enginebreather

The remaining components nray be fitted by
reversingthe procedure describedfor their rernoval.
